Definition from IAI: A collection of construction management
related objects (e.g. construction documents) in one place. It gathers all of
the related construction objects of different types as one package. It can be
used to track and allocation a specific construction management object quickly.
It is provided as a special type of IfcGroup, using the IfcRelAssignsToGroup
relationship to group the construction management related objects.
The following inherited relationships are used to reference the objects
from within the IfcCMDocPackage:
- IsGroupedBy : reference to the IfcRelAssignsToGroup
relationship keeping the linke to the grouped objects, e.g. to the IfcBudget,
IfcProjectOrder, IfcWorkPlan, IfcCostSchedule.
- HasAssociation : reference to the IfcDocumentSelect keeping
the link to documents associated to the doc package
- HasAssignment : reference to the IfcRelAssignsToControl
keeping the link to the approval object.
An instance of IfcCMDocPackage doesn’t contain the objects
directly; rather, it keeps all the references of the objects and maintain the
linkages to the objects.
